One in five children in Gaza City is suffering from malnutrition, according to the United Nations' Palestinian refugee agency. The agency reports that the number of affected children is rising daily, highlighting the worsening humanitarian crisis. Over 100 international aid organizations and human rights groups have issued warnings about the risk of mass starvation and are urging governments to intervene. Israeli authorities, who control supply entry into Gaza, deny imposing a siege and attribute malnutrition cases to Hamas.
